Abstract

The invention relates to an electrochromic material. The electrochromic material is an ion pair compound consisting of a functional group with a cathode electrochromic function and a functional groupwith an anode electrochromic function, and the ion pair compound has a chemical structural general formula (I), wherein the functional group with the cathode electrochromism function is a perfluoroalkyl and hydroxyl modified bipyridine salt, and the functional group with the anode electrochromism function is a phenazine derivative modified with a dibenzenesulfonic acid group. The electrochromic material has the advantages of high response speed and high contrast ratio. The invention further discloses a shell assembly comprising the electrochromic material and a mobile phone. The requirement for the appearance integrity of the mobile phone is met, and huge market application prospects are achieved.

Description

technical field [0001] The present invention relates to the technical field of electrochromism, in particular to a mobile terminal, a casing component, an electrochromic material and a preparation method thereof. Background technique [0002] With the continuous development of network communication technology, smart phones are more and more widely used. Mobile terminals such as smartphones and IPADs are generally equipped with optical devices (camera modules, ambient light sensors, flash lights, etc.), and the above optical devices need to be provided with light-transmitting areas at corresponding positions on the mobile terminal in order to receive and reflect light. The light-transmitting area on the existing mobile terminal is transparent, and the color-changing effect of the light-transmitting area on the incident light cannot be realized through the control of the mobile terminal. Visual aesthetics of the terminal. Contents of the invention [0003] In view of the a...
